This is a lot of 60 Brand New 30uF 250V (30MFD 250VDC) 5%  DC Noninductive Polypropylene, OPP (biaxially-oriented polypropylene) Metallized Wrap & Fill Axial Film Snubbers Capacitors.

Labeled as "Snubbers Capacitors"  Snubbers are energy-absorbing circuits used to suppress the voltage spikes caused by the circuit's inductance when a switch, electrical or mechanical, opens. The most common snubber circuit is a capacitor and resistor connected in series across the switch (transistor).

These TI ype 2101V round, axial film capacitors use polypropylene film and dual metallized electrodes for both self healing properties and high peak current carrying capability (dV/dt). This series features low

ESR characteristics, excellent high frequency and high voltage capabilities.

They are 53mm long and  27.5mm in dia and the leads are 41mm

Made by (TI) Tecate Group supplies high-quality ultracapacitors, capacitors, and electronic assemblies to customers worldwide.
